INERTIA-OPERATED CLIMBING TOY Filed May 24, 1947 2 ZlNVEETO-R A Z Z/W $4 ATTORNEY rod, the second of said loops having its efiective diameter and axial length so correlated with the rod diameter that the loop binds on the rod when tilted axially, a freely vibrating resilient member connected to the same part as the second of said loops in position to move back and forth in directions that transmit tilting force to the second of said loops and by such coaction alternately binding and releasing the second of said loops on the rod, and means to=limit the relative movement between said parts in one direction.

3. A toy comprising, a rod, a climbing figure consisting of two relatively movable parts, each i of said parts including a loop loosely encircling said rod, a freely vibrating resilient member connected to one of said parts, and movable in direcv tions to shift one of the loops alternately between v a position in which it is tilted with' respect to the axis of the rod and another position in which the.

loop is near enough to alignment with the rod to slide freely on said rod and a weight attached to said resilient member toincrease the inertia and .slow the normal period of vibration thereof.

4. A toy comprising, a rod, a climbing figure consisting of two relatively movable parts, each of said parts including a loop loosely encircling said resilient member to increase the inertia and slow the normal period of vibration thereof, and means to limit the relative movement between said parts in one direction. V

5. A toy comprising, a rod, a part constituting the torso, head and arms of a toy figure, a loop connected to said arms and loosely encircling said rod, a second partconstituting the legs of said figure, a loop connected to said legs and loosely encircling said rod, said loop having its effective diameter and axial length so correlated with the rod diameter that the loop binds on the rod when tilted axially, a pivotal connection between said parts, and a freely vibrating resilient member connected to said second part and adapted, when vibrating, to cause relative movement between said parts and to move said second part alternately to positions to cause its loop to bind on and free itself from said rod.

6. A toy comprising, a rod, a part constituting the torso, head and arms of a toy figure, a loop 4. connected to said arms and loosely encircling said rod, a second part constituting the legs of said figure, a loop connected to said legs and loosely encircling said rod, said loop having its effective diameter and axial length so correlated with the rod diameter that the loop binds on the rod when tilted axially, a pivotal connection between said parts, a freely vibrating resilient member connected to said second part and adapted, when vibrating,- to cause relative movement between --said parts and'to move said second part alternately to positions to cause its loop to bind on :and free itself from said rod, and means to limit direction which causes said last named loop to free itself from said rod.

7. A toy including, in combination, a straight rod,a cli'mbingfi'gure having one part constituting a torso, head and arms, and an element at the outer ends of the arms extending around the rod and connecting said upper part to the rod, said figure having a lower partconstituting its legs, a pivot at one end of the second part connecting the second part to the first part, an elementat the other end of the second part extending around the rodand having its width and axial length correlated with the cross section of the rod so as to bind on the rod when tilting axially with respect to the rod, a resilient member extending from the second part of the figure in a direction away from the rod and beyond the pivot, a weight attached to the resilient member for increasing its inertia and reducing its period of vibration, and means for limiting relative movement between the parts, said means including an abutment on the second part radially spaced from the pivot and in position to strikev against the first part when the second part is swung about the pivot by upward movement of the weight about the pivot.
